Commit 983b6297 ("dt-bindings: mfd: bd9571mwv: Convert to json-schema") converts bd9571mwv.txt to rohm,bd9571mwv.yaml, but missed to adjust its reference in MAINTAINERS. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. Repair this file reference in ROHM MULTIFUNCTION BD9571MWV-M PMIC DEVICE DRIVERS. Signed-off-by:

This debugfs isn't used by anyone, if we want to dump the contents of registers we should just convert the driver to regmap instead. I'm also excluding this from the device tree bindings when converting to YAML because it is not a real device, and device trees should only contain real physical devices. Delete it. Signed-off-by:

This rewrites the former text based AB8500 bindings in YAML. When the AB8500 bindings were first written (in 2012) we were not strict on some things and node names were definitely not standardized. This patch uses standard node names to most of the subnodes on the AB8500 and is accompanied by another patch fixing all the DTS files to conform to this. The bindings are not as perfect as newly written bindings would be, it is a best effort to deal with the legacy. Cc: devicetree@vger.kernel.org Signed-off-by:

Returning a non-zero value in an i2c remove callback results in the i2c core emitting a very generic error message ("remove failed (-ESOMETHING), will be ignored") and as the message indicates not further error handling is done. Instead emit a more specific error message and then return zero in .remove(). The long-term goal is to make the i2c remove prototype return void, making all implementations return 0 is preparatory work for this change.

For the CRC PMIC we end up with multiple IRQ domains with the same fwnode. One for the irqchip which demultiplexes the actual PMIC interrupt into interrupts for the various cells (known as the level 1 interrupts); And 2 more for the irqchips which are part of the crystal_cove_gpio and crystal_cove_charger cells. This leads to the following error being printed when CONFIG_GENERIC_IRQ_DEBUGFS is enabled: debugfs: File '\_SB.I2C7.PMIC' in directory 'domains' already present! Set the bus token of the main IRQ domain to DOMAIN_BUS_NEXUS to avoid this error, this also allows irq_find_matching_fwspec() to find the right domain if necessary. Note all 3 domain registering drivers need to set the IRQ domain bus token. This is necessary because the IRQ domain code defaults to creating the debugfs dir with just the fwnode name and then renames it when the bus token is set. So each one starts with the same default name and all 3 must be given a different name to avoid problems when one of the other drivers loads and starts with the same default name. Signed-off-by:

The Crystal Cove PMIC has a pin which can be used to connect the IRQ of an external charger IC. On some boards this is used and we need to have a cell for this, with a driver which creates its own irqchip with a single IRQ for the charger driver to consume. The charger driver cannot directly consume the IRQ from the MFD level irqchip because the PMIC has 2 levels of interrupts and the second level interrupt status register, which is handled by the cell drivers, needs to have the IRQ acked to avoid an IRQ storm.

This is a multifunction device with the following sub modules: - Regulator - RTC - Codec - Interrupt It is interfaced to the host controller using SPI interface by a proprietary hardware called PMIC wrapper or pwrap.

Clarify why we need to ping the watchdog before changing the timeout by quoting the MAX77714 datasheet. Signed-off-by:
-
Luca Ceresoli authored
The MAX77714 is a MFD chip whose watchdog has the same programming procedures as the MAX77620 watchdog, but most register offsets and bit masks are different, as well as some features. Support the MAX77714 watchdog by adding a variant description table holding the differences. All the features implemented by this driver are available on the MAX77714 except for the lack of a WDTOFFC bit. Instead of using a "HAS_*" flag we handle this by holding in the cnfg_glbl2_cfg_bits struct field the bits (i.e. the features) to enable in the CNFG_GLBL2 register. These bits differ among the two models. This implementation allows to avoid any conditional code, keeping the execution flow unchanged. Signed-off-by:

Add bindings for the MAX77714 PMIC with GPIO, RTC and watchdog. Signed-off-by:

Luca Ceresoli authored
The MAX77714 RTC chip is explicitly set to 24-hour mode in max77686_rtc_probe() -> max77686_rtc_init_reg() and never changed back to 12-hour mode. Accordingly info->rtc_24hr_mode is set to 1 in the same place and never modified later, so it is de facto a constant. Yet there is code to read 12-hour time, which is unreachable. Remove the unused variable, the unreachable code to manage 12-hour mode and the defines that become unused due to the above changes. Signed-off-by:
